Data Loss Prevention (DLP)

Protect your data with the Data Loss Prevention

Data loss is often unintentional. But that does not mean that accidental data leakage is any less risky. Companies face potential legal consequences and damage to their reputation. To protect their confidential customer data and ensure data security, therefore, they need a system for Data Loss Prevention (DLP).

Protect sensitive data with Data Loss Prevention

For effective data protection, companies need more than knowledge of the channels they use to process and forward confidential data; they also need an overview of where the information is stored. With this level of transparency, companies can set up a system to scan channels like e-mail, web and file directories for accidental data leakage and sound the alarm when necessary. Preventing data loss or data leakage also ensures that companies are able to meet regulatory and compliance requirements for data protection.

When is it the right solution?

There is a growing move to process and store data digitally in different locations. At the same time, regulatory and legal requirements for data protection are increasing. You need to make sure that your company meets these requirements.

Data Loss Prevention brings transparency over data flows and prevents confidential information from being shared with unauthorised persons, whether accidentally or intentionally. The measures also help to promote employee awareness of data protection and responsible handling of customer data.


To provide your business with optimal protection from unauthorised data leakage from your M365 applications, you can purchase DLP as a managed service using Microsoft DLP as an additional option from Swisscom.
